The author of the DC Thermostat Control document has expanded the idea to make a small improvement.

As noted in the above document, the original circuit draws a small amount of DC power even when the refrigerator is being run on gas. This is not a big deal unless you are boondocking for a long period. The updated approach requires one more relay, but eliminates that small DC power drain.
